asador near madrid

We are looking for a great asador with roast lamb experience near Madrid (sepulveda, segovia, etc) Have looked extensively at Maribel's guides (thanks Maribel - they are awesome!) and loved the idea of Figon Zute el Mayor. However, can't find any other info about it. We will be in Spain in December. Maybe that is not the time for roast lamb? Help please!

While Nazareno in Roa remains my favorite Asador (and Mauro in Penafiel my second) I wholeheartedly agree with the El Yantar recommendation in Pedraza. As Erica says the location is brillant and the lamb is among the best in the country.
